VF4 PS2 control scheme.

This is a question for those of you that have the PS2 version of VF4. I was just wondering what the control scheme is? DO you use the d-pad on the controller or the analogue stick or do you get a choice??Do you get to use the shoulder buttons as a set of three buttons pressed together a la DOA2: Hardcore??
THX!!!

i think, not fully sure, i switched the controls as soon as i started playing though. what's really good is that the controller setting are applied to the player profile, so you don't have to reconfigure at a friends place when you're in the midst of a tourney.
